FASTENING DEVICE.

Specification of Letters latent.

Patented Nov. 13,1917.

Application filed May 15, 1917. Serial No. 168,651.

To all whom it may concern:

Be it known that I, GERARD H. GERAERDTS, a citizen of the United States, and a resident of the city of New York, borough of the Bronx, in the county of Bronx and State of New 'York, have invented a new and Im proved Fastening Device, of which the following is a full, clear, and exact description. p,

The invention relates to walls, partitions and similar structures made of composition sheets or blocks such as plaster boards and the like, and providing a seat for receiving and retaining a reinforcing bar or the like toreinforce the partition.

The object of the invention is to provide a new and improved fastening device for holding the sheets or blocks in position and with the edges of adjacent sheets or blocks in uniform spaced relationfor the reception of plaster, mortar, cement or other plastic binding material. Another object is to permit the operator to quickly apply the fastening devices to facilitate the setting up of a wall or a partition.

In order to accomplish the desired result, use is made of a fastening device formed from a blank of sheet metal and having spaced retaining saddles extending in opposite directions and straddling adjacent sheets or blocks with a view to hold their opposite edges spaced apart.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a reduced sectional side elevation of a portion of an angular partition formed of plaster boards and in which the boards are held in place by the improved fastening devices;

Fig. 2 is a front elevation of one of the fastening devices;

Fig. 3 is an edge view of the same; 7

Fig. 4 is a similar view of the same bent for use at a corner;

Fig. 5 is a perspective view of the fastening device;

Fig. 6 is a similar view of a fastening device used at the junction of successive rows of plaster boards or blocks;

Fig. 7 is a face view of a modifiedform of the fastening device; and

Fig. 8 is an edge view of the same.

In Fig. 1 are illustrated two courses of plaster boards 10 and 11, of which the plaster boards in the lower course are fastened together at adjacent edges by a fastening device 12, shown in detail in Figs. 2, 3 and 5. The fastening device 12 is formed from a rectangular piece of sheet metal 13 from which are struck up approximately L- shaped tongues 14 and 15 extending in opposite directions and forming with the piece 13 saddles 16 and 17 for straddling the ad jacent margins of successive plaster boards. It will be noticed that the seats of the saddles 16 and 17 are spaced apart thus providing a space 20 between adjacent edges of successive plaster boards. The ends of the piece 13 and the tongues 14 and 15 are slightly curved to permit of readily engaging the saddles 16 and 17 with the successive plaster boards.

The plaster boards of the successive courses break joints, as plainly indicated in Fig. 1, and at the junction of the horizontal and vertical joints of the two adjacent courses are used fastenings such as illustrated in Fig. 6. Each of the fastenings 25 is made from a single piece of sheet metal 26 from the sides of which are struck up pairs of tongues 27, 28 and 29, 30't'o form two saddles 31 and 32 in which are seated the corresponding portions of the plaster boards at the joints mentioned. As the vertical joints are at the middle of the piece 26, the corresponding tongues 27, 28 or 29, 30 straddle adjacent plaster boards in a course, while the other pair of tongues straddle the same plaster boards in the adjacent course.

.When it is desired to join two partitions or walls at an angle, as indicated in Fig. 1, then the piece 13 of the fastening shown in Figs. 2, 3 and 5 is bent at its middle into angular position, as shown in Fig. 4, so that the saddles 16 and 17 extend at an angle one relative to the other to receive the corresponding plaster boards 10 of the partition walls to be joined.

The fastening illustrated in Figs. 7 and 8 is formed of a slnglepiece of band iron bent to provide a back 40, and return bent saddles 41 and 42' for receiving the adjacent plaster boards, the same as the saddles 16 and 17 above described. The back may be bent at its middle to form angular saddles, as indicated in dotted lines in Fig. 8. r

The fastening device shown and described 3 permits of readily connecting the plaster boards in a c urse ith ach other and also of connecting the plaster boards of a next following course wlth the plaster boards of the preceding course thus holding the plaster boards in position Without requiring other supporting or fastenin devices.

t Will also be notice that by spacing the saddles apart the adjacent edges of the plaster boards are held spaced apart for the reception of plaster, mortar, cement or other binding substance, to form a partition or wall of unbroken continuity and to securely fasten the adjacent plaster boards to each other throughout the entire length of their edges.

It is understood that the plaster used for a scratch coat is usually used for filling the joints between the edges of adjacent plaster boards While putting on the scratch coat.

Having thus described my invention, I claim as new and desire to secure by Letters Patent In a building construction, a fastening device for connecting plaster boards or blocks with each other and consisting of a flat continuous body portion and spaced apart pairs of integral saddles ofiset from the body portion and comprising seats and tongues projecting therefrom, said tongues lying in planes difi'erent to that of the body portion.
